*PC, headphones, and USB cable are not included.

*The DDJ-REV1 can be used with Serato DJ Lite free of charge. If you wish to use Serato DJ Pro, you will need to purchase a separate paid version of Pro.

*The image shows the controller connected by wire to adjust the master volume, but audio output is possible even without the cable.
Even without the cable, by inserting the transmitter into the PC, you can adjust the master volume using the PC's volume control.
Additionally, the speaker itself has volume controls, so you can adjust it there as well.

When connected by wire, there is a slight abnormal sound from the speaker, which is unavoidable due to the connection. It's at a level that's not noticeable when music is playing, but if it's a concern, it's best not to use the cable.
(While master adjustment on the controller is not possible, Trim and EQ are supported.)

This product allows for wireless music playback with no delay.
It's rare to find a wireless speaker with such minimal delay.
